Some videos work and some don't when I try to stream to my WP7. I can get everything to stream from PC to PC via the browser. I've purchased smart potato and have the trial for media buddy. they both have the same behavior.

When I try to open a recorded TV show it starts the stream but just sits at 0% buffering. This only happens with some of my recordings. At first I thought it could be a DRM issue but I can get these same shows to stream via the browser to different PCs.
